ʻO ka hale kūʻai kūʻai nui ʻo Switch Gigabit Ethernet - 24+4 Management Gigabit Switch JHA-S2404MG-28BC – JHA Detail:
24+4 Hoʻokele Gigabit Switch JHA-S2404MG-28BC
♦PhuahanaKAʻike maka
ʻO 24 + 4 Management Gigabit Switch kahi hoʻololi nonblocking maʻamau. Hāʻawi i nā awa 24 * 10/100 / 1000Base-T, 4 * 1000M SFP awa; 56Gbps hiki ke hoʻololi, 41.644Mpps i mua i ka hana, hiki ke hoʻololi i ka pūnaewele hiki ke hōʻoia i ka paʻa o ka pūnaewele a me ke koena o ka loulou ukana. e hāʻawi ana i ka bandwidth lawa no ka hōʻiliʻili ʻikepili a me ka hoʻololi ʻana i ka ʻikepili. He kūpono no nā ʻoihana liʻiliʻi a me nā ʻoihana liʻiliʻi, ka pūnaewele puni honua, nā hale kūʻai pūnaewele a me ka hoʻohana MAN.
♦ HuahanaKeyFmeaʻai
1 . Hana kiʻekiʻe
（1）Inith 56Gbps backplane kaha, ka hana kiʻekiʻe loa (1U TOR) ma kēia kahua;
（2）hardware routing, ua hiki i ka 41.644Mpps ka helu hoʻouna ʻana o ka uea māmā layer 2;
（3）hiki ke kau ʻia ma ka Metropolitan Area Network，a hāʻawi i nā ʻenehana kilomika hope loa;
（4）ethernet / IEEE802.3 nui packet (64 bytes a 1522 bytes)
（5）ʻO nā ʻeke jumbo a hiki i 9216 bytes
2 . Palekana a hilinaʻi
（1）provide DOS, DDOS, spoofing a me ka pale virus
（2）skākoʻo iā IEEE802.1x, hāʻawi i ka hōʻoia o ka mea hoʻohana ma ke awa, ka pale pūnaewele, ka mana palekana, a me ka ʻenehana hoʻomalu kulekele.
（3）rhoʻopaʻa i ka helu kiʻekiʻe loa o nā pūʻali e pili ana i ke awa, multi-binding Ethernet interface , hoʻonui i ka bandwidth a me ka redundancy system
（4）powerful ACL, kākoʻo L2-L4 kānana ʻikepili
（5）kulekelepapa kuhikuhi a me ka hooponopono kahe ana
3 . Mālama pono
（1）kākoʻo i ka hoʻonohonoho awa maʻalahi
（2）hiki ke mālama ʻia ma oPūnaewele, SNMP，etc
（3）skākoʻo i ka protocol XModem, hoʻohana i ka TFTP/ZMODEM no ka hoʻonui ʻana i ka polokalamu a me ka hoʻonui ʻana i ka BootRom
4 . Ka Mana Mana a me ka Hooponopono Hoolaha
（1）ʻike 'akomi a hoʻomalu i ka ʻino hoʻolaha, kākoʻo i ka ʻike ʻana i nā ʻeke IGMP, hoʻopaʻa pono i ke kahe ʻana o nā pā hoʻolaha.
（2）skākoʻo i ke ʻano duplex piha a me ka mana kahe o ka mode duplex hapa
（3）sE kākoʻo i ke kikowaena Ethernet e lawe ana i ka 1M e like me ka lōʻihi o ka pae no ka palena palena
